Vinyl aromatic monomers derived from dihydroeugenol (EBM) and guaiacol (GBM) were copolymerized, via a miniemulsion process, with aliphatic high oleic soybean oil (HOSBM), yielding emulsion polymers higher levels of biobased content. This fully renewable monomer feed generated broad range novel latexes, the number-average molecular weight varying 25,000–650,000 g/mol. Increasing content heighte...
